Abstract: The present invention relates to a multi-aziridine compound having: a) from 2 to 6 of the following structural units (A): whereby R?, R?, R1, R2, R3 and R4 are as defined herein m is an integer from 1 to 6; b) one or more linking chains wherein each one of these linking chains links two of the structural units A; and c) a molecular weight in the range from 600 Daltons to 5000 Daltons. The multi-aziridine compound can be used for example for crosslinking of for example carboxylic acid functional polymers dissolved and/or dispersed in an aqueous medium.

Abstract: Alkylating agents such as the sulphur and nitrogen mustard gases react with the silver salts of dialkyl or diaryl substituted thiophosphoric acids at ambient temperature, thereby producing cholinesterase-inhibiting compounds. This new reaction is applied to a few prior art detection reactions and determination procedures of cholinesterase-inhibiting compounds.

Abstract: Epoxidized mixed mellitate compounds useful as plasticizers for vinyl polymers such as polyvinyl chloride and which have markedly improved resistance to oils and hydrocarbon extraction have been prepared. The mixed mellitate plasticizers of this invention are trimellitates wherein two of the ester moieties are simple esters derived from monofunctional alcohols with the third ester moiety being a complex ester obtained by the reaction of a diol with an unsaturated monobasic acid subsequently epoxidized at the site of unsaturation.

Abstract: A ballistic missile is provided with an incendiary-type payload in which the incendiary composition is distributed around the ignition channel of the projectile within a plurality of successively disposed annular containers formed from a light metal alloy. Upon detonation, the individual containers forming the payload are successively ejected from the tail of the projectile in a ring-like pattern, and remain intact upon impact with the targeted terrain whereby the desired incendiary effect continues for a prolonged predetermined time.

Abstract: Mixed mellitate compounds useful as plasticizers for vinyl polymers, such as polyvinyl chloride homopolymers and copolymers, which have increased resistance to hydrocarbons have been prepared. The mixed mellitates of this invention are derived from trimellitic acid and trimellitic anhydride and contain two ester moieties derived from monofunctional alcohols and a third complex ester group obtained either by the reaction of a diol, a dibasic acid and a monofunctional alcohol or by the reaction of a diol and a monobasic acid.
